Because each career all participate in the social development at all. So I don"t agree if every career salary is different. I know it is difficult to change this. But I think if it happens. We can see a lot of people follow their dreams, the quality of the society will be better. And I see a smile on the face of the various professionals is increasing. I hope that someday someone would do this to be true. Although it is hard but I will hope and wait.
